Correct option is A
Correct answer: (a) light
How it fits all blanks:
· “the light was soft across the courtyard” — natural collocation.
· “asked us to light the candles” — correct verb usage.
· “with light luggage we climbed the stairs” — means not heavy.
· “painted a light blue” — common color description.
Why others don’t work:
· (b) hope — Doesn’t collocate with candles/luggage/color.
· (c) heavy — Cannot take “heavy the candles”; “heavy blue” is odd.
· (d) sight — “sight the candles” is incorrect; “sight blue” is wrong.
· (e) mist — “mist the candles” is incorrect; “mist luggage” and “mist blue” are wrong.
